Stream Processing: Understanding Message Brokers

TLDRLearn about stream processing and the architecture of message brokers. Discover the two main types of brokers: in-memory and log-based. In-memory brokers offer maximum throughput but can process messages out of order and lack durability. Log-based brokers ensure message order and durability, making them suitable for scenarios like sensor metrics and change data capture.

Key insights

🚀Stream processing involves communication between producers and consumers via events.

🔄In-memory message brokers handle loads and maximize throughput, but messages can be processed out of order and lack durability.

📝Log-based message brokers store messages in sequential order, ensuring message order and durability.

🎥In-memory brokers are suitable for scenarios where message order doesn't matter and maximum throughput is required, like encoding videos on YouTube.

🔍Log-based brokers are suitable for scenarios where message order and durability are crucial, like processing sensor metrics or capturing database changes.

Q&A

What is stream processing?

—Stream processing is the communication between producers and consumers through events.

What is the difference between in-memory and log-based message brokers?

—In-memory brokers offer maximum throughput but process messages out of order and lack durability, while log-based brokers ensure message order and durability.

When are in-memory brokers suitable to use?

—In-memory brokers are suitable for scenarios where message order doesn't matter and maximum throughput is required.

When are log-based brokers suitable to use?

—Log-based brokers are suitable for scenarios where message order and durability are crucial.

Can log-based brokers handle sensor metrics and change data capture?

—Yes, log-based brokers are suitable for processing sensor metrics and capturing changes in databases.
